Ten bogus frights of the past that shocked the world

by on Dec.24, 2005, under Links, News, Research, Science

Bird flu  

Bird flu has overshadowed the year 2005. The abominable virus claimed many bird lives in South East Asia before heading across Europe to Russia and Ukraine. However, the more scientists and officials talk about the deadly threat, the less credible it looks to people. Some people believe there is no such thing as bird flu. They think the whole story stemmed from the fights over the world market between the poultry producers. Others blame the pharmaceutical companies that are keen to spread panic and therefore make us buy more medicines. Which story should we believe in? Does the bird flu really exist? Does it pose a threat to humans? Did other threats of the worldwide proportions materialize?

It did not take long to tackle the problem; doctors found a pathogen and a vector – coronovirus and a palm cat, a viverrine animal normally used for food in China. However, the urgent measures could not stop another myth from spreading far and wide. The myth said that the SARS problem was made up to lower China’s economic growth and disrupt the exceedingly profitable tourist industry in South East Asia.

Academician of the Russian Academy of Sciences Lev Sandakhchiyev:

“Discovering a new more dangerous type of previously unknown coronavirus in the patients was direct evidence of a real threat. The ‘spinning’ of that epidemic stressed the importance of international cooperation. Many people did realize that humankind was destined to face new or recurrent infectious diseases. Therefore, a system of global and domestic monitoring is highly required.”

Spent nuclear fuel

Following a heated debate in 2001, the Russian president signed into law the bill on storage and reutilization of spent nuclear fuel from foreign nuclear power spent nuclear fuelplants. Specialists were unanimous while explaining to their opponents that spent nuclear fuel was not just the waste material from the nuclear industry. According to them, it is a high-tech product that can be used for extracting raw materials and energy. Despite potentially huge profits Russia could make (one ton of spent nuclear fuel costs $1 million; total estimated amount of spent nuclear fuel is 200 thousand tons), environmentalists have been relentless in their opposition to the new law.

Nikolai Shingarev, Director of the Information Center of the Federal Agency on Nuclear Energy:

“No spent nuclear fuel is being brought into Russia despite the law. We will probably sign the first contract under the new legislation for a small consignment of spent nuclear fuel from a research reactor in Uzbekistan. Today Russia is receiving nuclear waste from the nuclear plants built in the Soviet era in Ukraine ($370 thousand per 1 ton) and Bulgaria ($600 thousand per one ton). Reutilization waste materials will be stored in Russia only if the governments OKs the storage and only if fuel had been originally produced in Russia. 75% of revenues will be allocated for environmental programs and the remaining 25% will make part of local budgets.”

10 myths of the past, which never materialized

Steam-driven locomotive: serious scientists were asserting that cows would stop bearing offspring and produce milk at the sight of a locomotive. They also clamed that air would be squeezed out of train carriages at 20 km per hour and passengers will suffocate as a result.

Robot: intelligent machines will shake off dependence and take command of the world; humans would submit to the power of the machines.

Spacecraft: spacecraft were making holes in the atmosphere during the takeoff; the earth’s protective anti-radiation layer of the atmosphere will be eventually destroyed and thus the earth will be exposed to dangerous space particles.

Microwave oven: fried sausages can irradiate in the dark; radiation from food cooked in the oven will pile up in the human body and cause cancer.

Cell phone: radiation emitted by a cell phone receiver can affect the brain by liquefying it. Paradoxically, a cell phone phobia could not stop the massive spread of cellular communications all over the world.

Vaccination: the danger of vaccination is one of the longstanding fears in the world; the first objectors appeared shortly after the first vaccination campaign launched by Dr. Edward Jenner in 1796; many objected to vaccination in Russia at the end of the 1990s.

Environmental pollution: some people feared that the civilization would come to end by 2020 due to sky-high levels of industrial and communal pollution which should result in a lack of oxygen and poisonous evaporation.

Asbestos: Micro particles of asbestos cause lung cancer. Asbestos was produced in Canada and the USSR. Canadian asbestos companies went bankrupt following an anti-asbestos propaganda campaign instigated by the competitors. Russia’s asbestos makers have survived the bad times. The incidence rate of cancer in the town of Asbest does not exceed an average national incidence rate of cancer.

Global warming: industrial emissions of carbon dioxide cause the greenhouse effect that leads to overheating of the earth’s surface. Consequently, polar ice will melt away causing the global ocean level rise by one meter.

Ozone holes: Freon used in refrigerators and deodorants will destroy the ozone layer of the atmosphere, which protects Earth against the harmful effects of ultraviolet radiation. As a result, the number of cancer and other deadly diseases will grow.

I am not dead : Update

by on Dec.22, 2005, under Musings, Personal

Good news : I earned a GPA of 4.0/4.0 this semester. Just so if you don’t realize the significance of that, its the full score goddammit. Awesome. I have worked very hard this semester and i should say that eventhough my oral qualifier didn’t go that well, it sure did help me to refresh my ideas on engineering to such an extent that i could help even people with over 10 years of experience to understand what’s what !! 

This is absolutely fantastic. I have just now finished writing a 1-D neutron diffusion code with feedback in C# which works and got the news that i got a full score. Can this day get any better ?? It doesn’t matter actually since i still have almost 20 pages of my thesis to write in 3 days. That’s 7 pages/day atleast to write and believe me, writing a thesis is the worst thing you can get your hands on. Hopefully i will finish it off before next tuesday and will go on a vacation with a clear mind !

I actually have a lot to post and have saved them in my draft but right now, there’s just lot of work to be done. Maybe, i will post them all after new year’s. I will, surely, entertain you with lots of good thought provoking posts after the new year and as a bonus, will introduce you to my site. Until then, bye folks.

Perfection beyond sight

by on Dec.10, 2005, under Poetry

I long and ache in agony,
Agony filling my being in full.
Such perfection un-noticed
What doth anyone enjoy still ?

Every action in resonance of absolute perfection,
No remark uttered, music created,
Or video produced has even a slight fault,
This blend of perfection, can none but me see it still ?

Life, action, music and movie,
Nothing is pretense or at fault.
If any had a defect, so would the universe
Please, somebody claim that my premise is right.

Plutonium ?! What do i do with it

by on Dec.08, 2005, under Disaster, News, Nuclear

I had to quote this recent article at the Onion which a friend of mine forwarded to me.

The topic : “Terrorist Has No Idea What To Do With All This Plutonium”.

Yaquub Akhtar, the leader of an eight-man cell linked to a terrorist organization known as the Army Of Martyrs, admitted Tuesday that he “doesn’t have the slightest clue” what to do with the quarter-kilogram of plutonium he recently acquired.

“We had just given thanks to Allah for this glorious means to destroy the Great Satan once and for all, when [sub-lieutenant] Mahmoud [Ghassan] asked, ‘So, what’s the next step?’” Akhtar said. “I was at a loss.”

The 28-year-old fanatic said he and his associates had initially assumed that at least one member of their group had the physics and engineering background necessary to construct a thermonuclear device.

“Many eyes were upon me,” said Basim Aljawad, whose knowledge of physics did not extend to the principles of nuclear fission. “I make nail bombs. That’s it.”

My 2 cents of opinion on it : It is bloody funny and terribly scary. Funny because i can’t believe that someone had the means to get a raw material for a potential weapon and still do not have a clue on what to do with it. Scary because, obtaining plutonium, for motivated terrorists seems easy.

“I still believe in taking the lives of American civilians as revenge for the atrocities committed on our brothers, our wives, and our daughters,” Akhtar said. “I’m just not entirely sure it’s worth a headache this big.”

It is really sad to see such intense hatred against any nation, whoever it might be. On top of that, when such people also have the means to fulfill their wishes, the world doesn’t seem that safe anymore.

The Windows XP PC Boot Process

by on Dec.03, 2005, under Cool, Educational, Programming

  Power supply switched on. rarrow The power supply performs a self-test – When all voltages and current levels are acceptable, the supply indicates that the power is stable and sends the Power Good signal to the processor. The time from switch-on to Power Good is usually between .1 and .5 seconds.
  darrow    
  The microprocessor timer chip receives the Power Good signal. rarrow With the arrival of the Power Good signal the timer chip stops sending reset signals to the processor allowing the CPU to begin operations.
  darrow    
  The CPU starts executing the ROM BIOS code. rarrow The CPU loads the ROM BIOS starting at ROM memory address FFFF:0000 which is only 16 bytes from the top of ROM memory. As such it contains only a JMP (jump) instruction that points to the actual address of the ROM BIOS code.
  darrow    
  The ROM BIOS performs a basic test of central hardware to verify basic functionality. rarrow Any errors that occur at this point in the boot process will be reported by means of ‘beep-codes’ because the video subsystem has not yet been initialized.
  darrow    
  The BIOS searches for adapters that may need to load their own ROM BIOS routines. rarrow Video adapters provide the most common source of adapter ROM BIOS. The start-up BIOS routines scan memory addresses C000:0000 through C780:0000 to find video ROM. An error loading any adapter ROM generates an error such as:

XXXX ROM Error

where XXXX represents the segment address of the failed module.

  darrow    
  The ROM BIOS checks to see if this is a ‘cold-start’ or a ‘warm-start’ rarrow To determine whether this is a warm-start or a cold start the ROM BIOS startup routines check the value of two bytes located at memory location 0000:0472. Any value other than 1234h indicates that this is a cold-start.
  darrow    
  If this is a cold-start the ROM BIOS executes a full POST (Power On Self Test). If this is a warm-start the memory test portion of the POST is switched off. rarrow The POST can be broken down into three components:
The Video Test initializes the video adapter, tests the video card and video memory, and displays configuration information or any errors.
The BIOS Identification displays the BIOS version, manufacturer, and date. The Memory Test tests the memory chips and displays a running sum of installed memory.
  darrow   Errors the occur during the POST can be classified as either ‘fatal’ or ‘non-fatal’. A non-fatal error will typically display an error message on screen and allow the system to continue the boot process. A fatal error, on the other hand, stops the process of booting the computer and is generally signaled by a series of beep-codes.
  The BIOS locates and reads the configuration information stored in CMOS. rarrow CMOS (which stands for Complementary Metal-Oxide Semiconductor) is a small area of memory (64 bytes) which is maintained by the current of a small battery attached to the motherboard. Most importantly for the ROM BIOS startup routines CMOS indicates the order in which drives should be examined for an operating systems – floppy first, CD-Rom first, or fixed disk first.
Fixed Disk darrow    
  If the first bootable disk is a fixed disk the BIOS examines the very first sector of the disk for a Master Boot Record (MBR). For a floppy the BIOS looks for a Boot Record in the very first sector. rarrow On a fixed disk the Master Boot Record occupies the very first sector at cylinder 0, head 0, sector 1. It is 512 bytes in size. If this sector is found it is loaded into memory at address 0000:7C00 and tested for a valid signature. A valid signature would be the value 55AAh in the last two bytes. Lacking an MBR or a valid signature the boot process halts with an error message which might read:

NO ROM BASIC – SYSTEM HALTED

A Master Boot Record is made up of two parts – the partition table which describes the layout of the fixed disk and the partition loader code which includes instructions for continuing the boot process.

  darrow    
MBR With a valid MBR loaded into memory the BIOS transfers control of the boot process to the partition loader code that takes up most of the 512 bytes of the MBR. rarrow The process of installing multiple operating systems on a single PC usually involves replacing the original partition loader code with a Boot Loader program that allows the user to select the specific fixed disk to load in the next step of the process
  darrow    
Partition Table The partition loader (or Boot Loader) examines the partition table for a partition marked as active. The partition loader then searches the very first sector of that partition for a Boot Record. rarrow The Boot Record is also 512 bytes and contains a table that describes the characteristics of the partition (number of bytes per sectors, number of sectors per cluster, etc.) and also the jump code that locates the first of the operating system files (IO.SYS in DOS).
Operating System darrow    
Boot Record The active partition’s boot record is checked for a valid boot signature and if found the boot sector code is executed as a program. rarrow The loading of Windows XP is controlled by the file NTLDR which is a hidden, system file that resides in the root directory of the system partition. NTLDR will load XP in four stages:

1) Initial Boot Loader Phase
2) Operating System selection
3) Hardware Detection
4) Configuration Selection

  darrow    
NTLDR
Initial Phase
During the initial phase NTLDR switches the processor from real-mode to protected mode which places the processor in 32-bit memory mode and turns memory paging on. It then loads the appropriate mini-file system drivers to allow NTLDR to load files from a partition formatted with any of the files systems supported by XP. rarrow Windows XP supports partitions formatted with either the FAT-16, FAT-32, or NTFS file system.
  darrow    
NTLDR
OS Selection
BOOT.INI
If the file BOOT.INI is located in the root directory NTLDR will read it’s contents into
memory. If BOOT.INI contains entries for more than one operating system NTLDR will stop the boot sequence at this point, display a menu of choices, and wait for a specified period of time for the user to make a selection.
rarrow If the file BOOT.INI is not found in the root directory NTLDR will continue the boot
sequence and attempt to load XP from the first partition of the first disk, typically C:\.
  darrow    
F8 Assuming that the operating system being loaded is Windows NT, 2000, or XP pressing F8 at this stage of the boot sequence to display various boot options including “Safe Mode” and “Last Known Good Configuration” rarrow After each successful boot sequence XP makes a copy of the current combination of driver and system settings and stores it as the Last Known Good Configuration. This collection of settings can be used to boot the system subsequently if the installation of some new device has caused a boot failure.
  darrow    
NTLDR
Hardware Detection
If the selected operating system is XP, NTLDR will continue the boot process by locating and loading the DOS based NTDETECT.COM program to perform hardware detection. rarrow NTDETECT.COM collects a list of currently installed hardware components and returns this list for later inclusion in the registry under the HKEY_LOCAL_MACHINEHARDWARE key.
  darrow    
NTLDR
Configuration Selection
If this computer has
more than one defined Hardware Profile the NTLDR program will stop at
this point and display the Hardware Profiles/Configuration Recovery
menu.
rarrow Lacking more than one Hardware Profile NTLDR will skip this step and not display this menu.
  darrow    
Kernel Load After selecting a hardware configuration (if necessary) NTLDR begins loading the XP kernel (NTOSKRNL.EXE). rarrow During the loading of the kernel (but before it is initialized) NTLDR remains in control of the computer. The screen is cleared and a series of white rectangles progress across the bottom of the screen. NTLDR also loads the Hardware Abstraction Layer (HAL.DLL) at this time which will insulate the kernel from hardware. Both files are located in the \system32 directory.
  darrow    
NTLDR
Boot
Device Drivers
NTLDR now loads device drivers that are marked as boot devices. With the loading of these drivers NTLDR relinquishes control of the computer. rarrow Every driver has a registry subkey entry under HKEY_LOCAL_MACHINE
\SYSTEM\Services. Any driver that has a Start value of SERVICE_BOOT_START is considered a device to start at boot up. A period is printed to the screen for each loaded file (unless the /SOS switch is used in which case file names are printed.
  darrow    
Kernel Initialization NTOSKRNL goes through two phases in its boot process – phase 0 and phase 1. Phase 0 initializes just enough of the microkernel and Executive subsystems so that basic services required for the completion of initialization become available.. At this point, the system display a graphical screen with a status bar indicating load status. rarrow XP disables interrupts during phase 0 and enables them before phase 1. The HAL is called to prepare the interrupt controller; the Memory Manager, Object Manager, Security Reference Monitor, and Process Manager are initialized.

Phase 1 begins when the HAL is called to prepare the system to accept interrupts from devices. If more than one processor is present the additional processors are initialized at this point. All Executive subsystems are reinitialized in the following order:

1) Object Manager
2) Executive
3) Microkernel
4) Security Reference Monitor
5) Memory Manager
6) Cache Manager
7) LPCS
8) I/O Manager
9) Process Manager

  darrow    
I/O Manager The initialization of I/O Manager begins the process of loading all the systems driver files. Picking up where NTLDR left off, it first finishes the loading of boot
devices. Next it assembles a prioritized list of drivers and attempts to load each in turn.
rarrow The failure of a driver to load may prompt NT to reboot and try to start the system using the values stored in the Last Known Good Configuration.
  darrow    
SMSS The last task for phase 1 initialization of the kernel is to launch the Session Manager Subsystem (SMSS). SMSS is responsible for creating the user-mode environment that provides the visible interface to NT. rarrow SMSS runs in user-mode but unlike other user-mode applications SMSS is considered a trusted part of the operating system and is also a native application (it uses only core Executive functions). These two features allow SMSS to start the graphics subsystem and login processes.
  darrow    
win32k.sys SMSS loads the win32k.sys device driver which implements the Win32 graphics subsystem. rarrow Shortly after win32k.sys starts it switches the screen into graphics mode. The Services Subsystem now starts all services mark as Auto Start. Once all devices and services are started the boot is deemed successful and this configuration is saved as the Last Known Good Configuration.
  darrow    
Logon The XP boot process is not considered complete until a user has successfully logged onto the system. The process is begun by the WINLOGON.EXE file which is loaded as a service by the kernel and continued by the Local Security Authority (LSASS.EXE) which displays the logon dialog box. rarrow This dialog box appears at approximately the time that the Services Subsystem starts the network service.

Choosing good passwords

by on Dec.02, 2005, under Computers, Cool, Educational

A farewell mail from one of Apple’s security professionals. Derrick Donnelly, in his farewell mail, made these very interesting suggestions for choosing a good password.

My final words

Remember security starts at the keyboard in front of you:

A 6 character password has about fifty six billion (56,800,235,584) possibilities and the average computer (the G5 is even faster) can try all combinations (crack them) in 2.5 hours.

A 7 character password has about three and a half trillion (3,521,614,606,208) possibilities and a computer can try all combinations in about 1 week.

An 8 character password has about two hundred trillion (218,340,105,584,896) possibilities and a computer can try all its combinations in about a year.

A 9 character password would take about 70 years for a computer to try all combinations.

They say the chips coming in about a year could half these times! Now if you do not want to wait for next year’s chip, you can always put 2 computers in parallel and half the time. In theory you could put 365 computers in parallel and break 8 character passwords in just over a day (Virginia Tech just put 1100 G5s in parallel). Do you think hackers have friends?

Computers have a lot more time on their hands than we do and most of the bad guys don’t have jobs. The next person asking for your social security number could be just a few clicks away from your stock options.

If you just got a chill down your back or just got a little paranoid; good, my work is done.

Use an 8 character password (9 characters is better)… You would make this security professional very happy if you would change your passwords after you read this e-mail : )

You can learn more about choosing good Passwords. And hey, do follow them !

On a sidenote, I remember learning to code during the under grad years just for the thrill of cracking passwords. I can still feel how beautiful it was when i did manage to do it. Sheer bliss. I understood then, on why people take so much effort to hack into classified sites and just play around with files until they make one stupid mistake and get caught.

It is the sheer satisfaction of the EGO … The Ego Trail that keeps us going.

Hack sleep and screw yourself

by on Nov.18, 2005, under Fun, Health, Musings, News, Research

The past few days have been the most stressful period as far as my gray cells can look back in time. The downside of all the stress is that my sleep cycle is terribly screwed up and there is no telling what the schedule for my sleep will be, say tonight. Although, sacrificing a bit of sleep does give me a lot more time to work rather than doze off for some rest, the body cycle, my concentration and focus have started to waver quite a bit.

I got intrigued and set about to analyze the effects of such a sleep starvation on the mind, health and found puzzling pieces of facts. Here i present to you, my review article on “Sleep deprivation and its ill-effects”.

Disclaimer : This is a review post about the different articles i found with information, facts from those sites on hacking sleep, sleep cycles, problems that sleep deprivation can induce and my thoughts to manage a balance between lesser sleep and better health. Read on if you want to learn all about ‘Sleep’. Or so i lure you !

Sleep

Until the 1950s, most people thought of sleep as a passive, dormant part of our daily lives. We now know that our brains are very active during sleep. Moreover, sleep affects our daily functioning and our physical and mental health in many ways that we are just beginning to understand.

During sleep, we usually pass through five phases of sleep: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep. These stages progress in a cycle from stage 1 to REM sleep, then the cycle starts over again with stage 1 (see figure 1). We spend almost 50 percent of our total sleep time in stage 2 sleep, about 20 percent in REM sleep, and the remaining 30 percent in the other stages. Infants, by contrast, spend about half of their sleep time in REM sleep.

The amount of sleep each person needs depends on many factors, including age. Infants generally require about 16 hours a day, while teenagers need about 9 hours on average. For most adults, 7 to 8 hours a night appears to be the best amount of sleep, although some people may need as few as 5 hours or as many as 10 hours of sleep each day. Women in the first 3 months of pregnancy often need several more hours of sleep than usual. The amount of sleep a person needs also increases if he or she has been deprived of sleep in previous days. Getting too little sleep creates a “sleep debt,” which is much like being overdrawn at a bank. Eventually, your body will demand that the debt be repaid. We don’t seem to adapt to getting less sleep than we need; while we may get used to a sleep-depriving schedule, our judgment, reaction time, and other functions are still impaired.

Although scientists are still trying to learn exactly why people need sleep, animal studies show that sleep is necessary for survival. Sleep appears necessary for our nervous systems to work properly. Too little sleep leaves us drowsy and unable to concentrate the next day. It also leads to impaired memory and physical performance and reduced ability to carry out math calculations. If sleep deprivation continues, hallucinations and mood swings may develop. Some experts believe sleep gives neurons used while we are awake a chance to shut down and repair themselves. Without sleep, neurons may become so depleted in energy or so polluted with byproducts of normal cellular activities that they begin to malfunction. Sleep also may give the brain a chance to exercise important neuronal connections that might otherwise deteriorate from lack of activity.

With this brief introduction into the physics of Sleep, let us see what some of the recent articles and posts have to say about ‘Polyphasic sleep’, ‘Hacking Sleep’ and their effects.

Polyphasic sleep

Polyphasic sleep is a sleep pattern specification intended to reduce sleep time to 2–5 hours daily. This is achieved by spreading out sleep into short naps of around 20–45 minutes throughout the day. This is supposed to allow for more waking hours with relatively high alertness.

The method uses natural human sleep mechanisms to maximize alertness when sleep time needs to be minimized. However, it requires a rigid schedule which makes it unfeasible for most people. It can work well for those engaged in activities which do not permit lengthy periods of sleep (e.g. sailors).

Again, several articles have been written recently about Polyphasic sleep and the attention it has gathered, forces me to look into the subject in detail. But first, let us look at the Sleep cycles and understand the different phases involved during a normal sleep routine before trying to attempt Polyphasic sleep.

To start off, let us look at a great article which has detailed analysis on the sleep cycles, phases, physiological effects, the natural rythm and factors that can affect a normal sleep. The article is very formal in nature and looks more like a technical paper, but we have to note that it thoroughly analyzes the different components that induce sleep, namely

1) The circadian component and
2) The homeostatic component

The author then talks about some of the habits that are misconceptualized in society about sleep and talks about some of the myths and discusses the implications of each. I definitely did learn a lot in this part. I am sure you will too !

Here’s a detailed look at the sleep cycles, the average duration of each cycle and which cycle is important to feel refreshed and to avoid the uneasy feeling even after 8 hours of sleep.

In the course of the night, we alternately enter two phases of sleep :

  • NREM sleep (named for non-Rapid Eye Movement) – Scientists believe that NREM is the critical moment of memory consolidation in which the hippocampus(central memory switchboard of the brain) works as the neural trainer for the neocortex in which long-term memories will be stored. Those long-term memories cannot be formed without entering appropriates stages of the sleep cycle! You cannot learn effectively if your sleep gets cut short in the morning. Or if it gets interrupted during the night. Even if you try to sleep 15 hours per day in short pieces of interrupted sleep, your learning results will be dismal! Long story short, No NREM -> Not a solid long term memory.
  • REM sleep (named for Rapid Eye Movement) – The brain in REM sleep is a hard-working brain that has little to do with the notion of energy-conservation and rest in sleep.

To learn more on sleep cycles, read the above article and The power of the Sleep Cycle. There are some interesting quotes in the article about ways to improve the alertness, fitness and health even with lesser sleep if proportioned rightly. This is very interesting.

Another article which created quite a buzz on ‘Polyphasic sleep’ is the ‘Uberman’s sleeping schedule‘. The recent article over at Kuro5hin talks about the Uberman’s sleeping schedule or Polyphasic sleep where the author manages to get just 3 hours of sleep everyday and freeing more time to work with 5-6 20-30 min short naps.

The idea behind this is to maximize the REM(rapid eye movement) sleep when your brain is still mostly active, conjuring dreams that we see. Interesting concept again but not quite workable if you don’t have the luxury to control your working time. Also, the effects mentioned in the article are only short term and the author has no clue about the long term effects of such a Uberman schedule. Definitely a risky bet IMO.

After reading the previous article, i was searching to find the effects of such a polyphasic sleeping schedule and stumbled upon another article which quotes and mentions the effects of polyphasic sleep from journal articles. Let us quote from ‘Ubersleep? Hacking Sleep? Stupid!

Like i guessed, there are some serious side effects to such polyphasic sleep. Here’s a small list of the long term effects that you need to be aware of before trying any of this.

  • Your health will suffer
  • Less sleep equals more fat
  • People who sleep normally, live longer
  • You increase your chances of having a car wreck

Some of it, i could have guessed by intuition but some of it has factual data to support it.

Based on the previous article, i suspected that maybe obesity is somehow related to sleep deprivation. Reason : I have been eating very less over the past few days combined with lesser sleep but i have still managed to gain over 3lbs in weight in the past month.

This article argues that ‘lack of sleep’ is a factor for obesity. The author also mentions couple of good stories and research attempts to discern the effects of the polyphasic sleep.

But oh well, no one is stopping anyone from trying polyphasic sleep but IMHO, dont try it, without researching the full effects of what it will do to you !

Moving on, i did find more scientific articles that have made observations on ‘What Losing Sleep Does to a Body‘.

While many aspects of sleep remain a mystery — including exactly why we sleep — the picture that appears to be emerging is that not sleeping enough or being awake in the wee hours runs counter to the body’s internal clock, throwing a host of basic bodily functions out of sync.

“Lack of sleep disrupts every physiologic function in the body,” said Eve Van Cauter of the University of Chicago. “We have nothing in our biology that allows us to adapt to this behavior.”

The amount of necessary sleep varies from person to person, with some breezing through their days on just a few hours’ slumber and others barely functioning without a full 10 hours, experts say. But most people apparently need between about seven and nine hours, with studies indicating that an increased risk for disease starts to kick in when people get less than six or seven, experts say.

–Holy crap. If what they say is true, then i might have actually reduced my life span by atleast 10 yrs now for sleep starving myself over the past 6-7 years. Read this article too to learn some of the recent research activities being done to find out exactly the detrimental effects of inadequate sleep.

Another scientific article i found was ‘Down for the Count‘ which observes the sleeping habits of mammals in general.

“People who don’t have REM sleep are remarkably normal,” Dr. Siegel said. “There’s no evidence for any intellectual or emotional problems.”

So why do mammals and birds have REM sleep at all? “The best answer I can come up with is that it’s there to prepare you for waking,” Dr. Siegel said. “When the important work of sleep is done, REM sleep just makes you as alert as you can be while you’re asleep.”

–Well that rules out REM maximizing Ubersleep for me. Goodbye polyphasic sleep.

Now a few other articles suggest that “Deep Sleep May Be Genetic”. Eventhough the argument sounds appealing, i am very skeptical about the validity of such a thing. I think that deep sleep is directly related to a person’s stress level and ability to calm his mind. Hence, to get a deep sleep, I think that the psyche of a person matters and not the genes he derived from his parent. Well, i could be way off or closer than you think, but let further research prove me wrong.

In the light of learning scientifically about sleep, i feel obliged to link to another article that is based on sleep research. The article ‘Deep sleep short-circuits brain’s grid of connectivity‘ discusses how the brain functions during deep sleep. Here’s a quote from the article.

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain – regions that during waking hours are a bustling grid of neural dialogue – apparently lose their ability to communicate effectively, causing consciousness to fade.

After reading so much about the different kinds of sleep cycles, methods to optimize sleep, i definitely felt that there is one other thing all the previous authors missed out. Meditation.

Meditation builds up the brain

What effect meditating has on the structure of the brain has also been a matter of some debate. Now Sara Lazar at the Massachusetts General Hospital in Boston, US, and colleagues have used MRI to compare 15 meditators, with experience ranging from 1 to 30 years, and 15 non-meditators.

They found that meditating actually increases the thickness of the cortex in areas involved in attention and sensory processing, such as the prefrontal cortex and the right anterior insula.

“You are exercising it while you meditate, and it gets bigger,” she says. The finding is in line with studies showing that accomplished musicians, athletes and linguists all have thickening in relevant areas of the cortex. It is further evidence, says Lazar, that yogis “aren’t just sitting there doing nothing”.

The growth of the cortex is not due to the growth of new neurons, she points out, but results from wider blood vessels, more supporting structures such as glia and astrocytes, and increased branching and connections.

-The research reinstates what we already know about the oriental methodologies involving meditation and the benefits of it. Theories apart, i have been practising meditation for well over 2 years although not very regularly and from my personal experience i can say for sure that if you do it right, it can compensate for hours of sleep deprivation. At the end of the meditative session, i usually feel alert, more conscious, and more alive. The symptoms of drowsiness and lethargy vanish and i am ready to do more work. It is important to understand the process of meditation to get the maximum benefit. The vital component is the ‘breathing’, which will determine how peaceful a feeling you are going to reach and the steadiness of your breathing will quicken the process. I am no where near an expert on this and i suggest that if you are interested, read up more or ask a professional.

Anyway, IMHO, meditation can definitely help me more than any theory on polyphasic sleep. But hey, no one is stopping you to try something different. And if it works, i’d be happy to know.

Diverging from the topic a little bit, on the topic of Alarm clocks, here’s another interesting article : ‘Alarm clocks are bad. How to wake up and feel better‘.

If you are one of those persons who relies heavily on alarm clocks to wake up in the morning, like i do, then you already know how irritating the sound of the alarm can be. But is there an easier way to wake us up with an alarm, without abruptly disrupting the sleep but to slowly ease in to getting up, and to avoid that groggy feeling after sleep ? Yes. The article provides an innovative method that aims to do that albeit expensive. In the end, another cool idea and a nice theory !

Here’s another scary finding ! An article that took sleep deprived doctors as test subjects has recently concluded that the attention, vigilance, driving skills suffer as much from long work hours & overnight shifts as from blood alcohol level of 0.04%.

Read more about ‘Lack of sleep affects young doctors just like alcohol‘.

In the end, there seems only one way to beat the time crunch. A ‘28 hour day schedule‘. I have thought about such an idea before but never realized that someone else would be interested on similar lines. Here’s the crux of the idea.

We know that there are 24 hours & 7 days in a week, a total of 168 hours. Instead, if we have 28 hours/day with a 6 day week period, we could have longer hours in a day, more time to work and more time to sleep. Voila ! But us humans, err, me i am sure, will still manage to work for 22 hours and get only 6 hours of sleep. Now i wonder how that would be like !

Conclusion :

Sleep well. Eat well. Life is probably(?!) not worth screwing around. My advice : Screw polyphasic sleep. Embrace meditation.

You only have one life to live. Enjoy it while it lasts.

That which drives me

by on Nov.08, 2005, under Poetry

With every passing second, a new life,
With every uttered word, a perfect statement,
With every action done, a perfect event,
Such perfection, this harmony, beyond limits.
Is there a need for reason to write poetry ?

Wings spread in absolute grace,
The rythm running through the veins,
Every moment, every syllable born,
Eternal bliss beyond.
Do i need another reason to write poetry ?

Back with a vengeance

by on Nov.02, 2005, under Musings, Personal

I have gotten over the fact that i screwed up my oral and am back to my old self, bubbling with over-confidence ;) . Anyhoo, this has been a very very bad week and have been doing lots of work on my research, assignments, grading and reading for tests.  

Seems like Nature has a way to test each individual at the worst possible times ! How challenging, isn’t it ?! I have kept up till now, sacrificing a lot of my sleep this week but am not sure if i can hold on for another 2 days with an average of 3 hrs sleep. Lets hope i do make it.

Btw, i’ve got a beautiful and informative article that i am writing myself, based on various references about the goodness of sleep. Yes. You heard me right. Sleep. So grab your pillows and place your laptop by the bedside to read all about the importance of getting sleep and how it can adversely affect you and your health, if you dont taste enough of it !

Watch out for the article over the weekend. Until then, checking out.

Ironically unsatisfied

by on Oct.22, 2005, under Poetry

A session in glory after a long wait,
Whither thy will to learn.
Failing miserably even the simplest test
This mind feels sore and in unrest.

Basics, complicated by words,
Eludes the mind in vigorous anxiety.
Never has this feeling come before
Such fear, in the path of passion, flesh devoured.

All my professor wanted was answers,
Answers that i knew,
but too dumb to say ;
Anxiety it seems, cripples the ego of the beast.

The result doth not matter.
The energy dissipated in fulfilling the passion,
Eats away the peace without rest
What shall i do, to neutralize this irony ?

At last, i passed’em all !

by on Oct.21, 2005, under Musings, Nuclear, Personal

Yes, i passed all my qualifiers. I am officially a PhD candidate now !

Next, i am completely disappointed with the way i performed today. Eventhough, i am sure that my prof would have argued in favor of me, i feel disgusted with the way i stared blankly for some of the questions – some because i couldn’t remember and some because i couldn’t understand the russian accent of another prof. I definitely didn’t blurt out everything i knew and made myself look like an unprepared idiot. Overall, i did much worse than i could have possibly imagined.

Ironically i did pass and now i do not know how to feel. Am i supposed to feel bad about how i flunked this or am i supposed to feel happy that i did manage to pass.

Either way, i am out of here to get a drink.

Not quite a PhD candidate yet

by on Oct.18, 2005, under Musings, Nuclear, Personal

Yup. I’ve got another round of oral qualifier and they’ve decided to conduct it this Friday. Can’t wait for the damn thing to get over when i can breathe the free air and say ‘I am a PhD student’ !

Hopefully, all the drinking after the written qualifier results hasn’t eaten away my gray cells to an irreparable extent. Well, gotta go and read more and start preparing for the test more seriously. Other than that, just the usual things : research, coding, classes, assignments and presentations.

Will chip in again with a post on Friday to write about the oral experience ;) Until then, adios amigos.

Quotes – 7

by on Oct.17, 2005, under Quotes

This entry is part 10 of 29 in the series Quotes

“Beware the leader who bangs the drums in war to whip the citizenry into a patriotic fervor, for patriotism is indeed a double-edged sword. It both emboldens the blood, just as it narrows the mind.And when the drums of war have reached a fever pitch and the blood boils with hate and the mind has closed, the leader will have no need in seizing the rights of the citizenry, infused with fear and blinded by patriotism, they will offer up all their rights unto the leader and gladly so.

How do I know ? For this is what I have done. And I am Ceasar.”

- An experienced leader’s pragmatic words.
